Viking expansion is the process by which the Vikings sailed most of the North Atlantic, reaching south to North Africa and east to Russia, Constantinople and the Middle East as looters, traders, colonists and mercenaries. Vikings under Leif Ericsson, the heir to Erik the Red, reached North America and set up a short-lived settlement in present-day L'Anse aux Meadows, Newfoundland and Labrador, Canada. Longer and more established settlements were formed in Greenland, Iceland, Great Britain and Normandy.
